Answer: \dfrac{3}{4}

Step-by-step explanation:

In fraction, we consider natural number "1" as the whole part.

Given : A certain bag of potting soil is \dfrac{1}{4} peat moss, and the rest is dirt .

Then , the part of dirt will be :-

1-\dfrac{1}{4}=\dfrac{4-1}{4}=\dfrac{3}{4}

Therefore, the part of bag is dirt =\dfrac{3}{4} or three-fourth.

If you do the math you'll get 3/4 of the bag is dirt.

Suppose 15% of x equals 20% of y. What percentage of x is y ?
WINSTONCH [101]

Answer:

x = 133\frac{1}{3} of y

Step-by-step explanation:

Given:

15% of x equals 20% of y

So,

0.15x = 0.20y

so

x = 0.20 y / 0.15

x = 1.3333y

x = 133\frac{1}{3} of y

A worn, poorly set-up machine is observed to produce components whose length X follows a normal distribution with mean 14 centim
Akimi4 [234]

Answer:

74.86% probability that a component is at least 12 centimeters long.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 14

Variance is 9.

The standard deviation is the square root of the variance.

So

\sigma = \sqrt{9} = 3

Calculate the probability that a component is at least 12 centimeters long.

This is 1 subtracted by the pvalue of Z when X = 12. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{12 - 14}{3}

Z = -0.67

Z = -0.67 has a pvalue of 0.2514.

1-0.2514 = 0.7486

74.86% probability that a component is at least 12 centimeters long.

a sixteen sided number cube has the numbers 1 through 16 on each face. each face is equally likely to show after a roll. what is
solong [7]
The possibilities of an even number are  2,  4,  6,  8,  10,  12,  14, and  16 .

The possibilities of an odd prime are  3,  5,  7,  11,  and  13.

8 even numbers + 5 odd primes  =  13 possibilities of success

                                                 out of 16 total possible outcomes.

Probability of success  =  13/16 =   0.8125  =  81.25% .

Rounded to the nearest thousandth, it's 0.813 .

Using translation concepts, it is found that the transformations to create function d are given as follows:

  • Horizontal shift right 1 unit.
  • Vertical shift up 5 units.
  • Frequency multiplied by 2.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent cosine function is given by:

f(x) = cos(x).

The translated function is given by:

d(x) = cos(2x - 1) + 5.

Which means that:

  • 1 was subtracted in the domain, hence the was a horizontal shift right 1 unit.
  • 5 was added in the range, hence there was a vertical shift up 5 units.
  • There was a multiplication by 2 in the domain, hence the frequency is multiplied by 2.
